2 Claims.

My invention relates to means for freeing air of foreign bodies such assmoke, dust and noxious gases. It primarily has for an object to providea unit which can be employed for a variety of objects as for example asmoke consumer for furnaces, a draft and air circulator for furnaces, anair circulator, cleaner and moistener for rooms, an air purifier andcooler in summer time and an air purifier and warmer in winter time.

Further the invention has for its object to provide a unit for each andall of the above purposes which will operate with a small power motorand will therefore cost very little to operate.

Again it is an object to provide a unit of the character stated of asimple inexpensive construction which will be automatic in action andwill readily serve its intended purpose.

Other objects will in part be obvious and in part be pointed outhereinafter.

To the attainment of the aforesaid. objects and ends the invention stillfurther resides in the novel details of construction, combination andarrangement of parts, all of which will be first fully described in thefollowing detailed description, and then be particularly pointed out inthe appended claims, reference being had to the accompanying drawings,in which:

Fig. 1 is a vertical, longitudinal section of the unit.

Fig. 2 is a horizontal section on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal section on the line 33 of Fig. 1.

Fig. 4 is a cross section on the line 44 of Fi 1.

Fig. 5 is an enlarged detail section of a portion of the filter.

In the drawings, in which like numerals and letters of referenceindicate like parts in all of the figures, i represents a tank ofsuitable size and material in which is located a cross partition 2 whosepurpose is to divide the tank into two separate compartments whichcommunicate with one another only through an aperture 3. One of thecompartments A is the water inlet and supply compartment, while theother B is the air treating compartment.

The tank is suitably supported, as by legs 4, and it has an opening 5 inits bottom under which is removably secured the sediment trap 6, a draincock 1 being provided for drawing off the liquid contents of thecompartment B when desired.

Water is supplied from any suitable source via pipe 8 and float valvedevice 9 to compartment A.

When the water level in compartment A reaches hole 3 the water will passthrough compartment B below the filter-screen Il|2 until it reaches alevel with the water in compartment A at which time float valve 9 willshut off. The water level is so adjusted that it never reaches thefilterscreen ll--l2.

The filter-screen comprises a pair of wire-mesh screens between which isplaced a cloth or other suitable filtering means which will permit airto pass through but which will hold back dust, smoke and the like. Sothat it may be renewed when renewal is desired, the filter-screen li -l2rests on flanges Iii secured to the side walls of the tank I.

I3 designates the cover for the tank. It supports an inlet duct It whichprojects through a tight hole It: in the screen filter lll2 and has itsdischarge end immersed in the water (or chemical fluid when such isused) in compartment B of tank I. The cover I3 also carries the outletduct l5 communicating with the suction blower IT, the latter beingpreferably of the type used in vacuum cleaners and which is operated bya small electric motor l8.

The blowers outlet duct is indicated by l 9, and 20 indicates a Tcoupling, the branch outlet of which is capped at 2| when not in use. Tothe outlet end of the duct 19 may be connected a filter bag 22 ofsuitable construction and material, such for instance as that used inthe well known vacuum cleaner bags.

When the unit is to be used the pipe 8 is connected with a suitableconstant source of water supply.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought that the complete construction,operation and advantages of the invention will be clear to those skilledin the art.

What I claim is:

1. In apparatus of the class described, a unitary structure comprising atank, divided by a partition into two side-by-side chambers, one chamberconstituting a Water supply chamber and the other a gas Washing chamber,a cover for said tank, means securing said cover to said tank over saidchambers, an inlet pipe carried by said cover and extending into saidWashing chamber, an outlet pipe and a suction-blower with motor mountedon and carried by said cover, a filter screen in said washing chamberbelow the top thereof and serving as a partition for said washingchamber, dividing it into an upper air space and a lower liquid space,and means to admit liquid to said water supply chamber, saidfirstmentioned partition having means to pass liquid from said supplychamber to said washing chamber at the level at which the liquid is tobe maintained in said washing chamber, said inlet pipe projectingthrough said screen and having its delivery end continuously immersed inthe liquid in the washing chamber and said outlet pipe communicatingwith the air space above the screen in said washing chamber.

2. In apparatus of the class described, a unitary structure comprising atank, divided by a partition into two side-by-side chambers, one chamberconstituting a water supply chamber and the other a gas washing chamber,a cover for said tank, means securing said cover to said tank over saidchambers, an inlet pipe carried by said cover and extending into saidwashing chamber, an

outlet pipe and a suction-blower with motor mounted on and carried bysaid cover, a filter screen in said washing chamber below the topthereof and serving as a partition for said washing chamber, dividing itinto an upper air space and a lower liquid space, and means to admitliquid to said Water supply chamber, said firstmentioned partitionhaving means to pass liquid from said supply chamber to said washingchamber at the level at which the liquid is to be maintained in saidwashing chamber, said inlet pipe projecting through said screen andhaving its delivery end continuously immersed in the liquid in thewashing chamber and said outlet pipe communicating with the air spaceabove the screen in said washing chamber, said tank having an opening inits bottom and a dirt collecting reservoir removably secured to saidtank under said opening for purposes described.
